Walk upto the door, ring bell or knock door. When person opens the door, look them in the eye and ask them if they'd like a window cleaner to clean their windows every X weeks.If they say yes please, take their details. If they say no, say "Thank you for your time, have a nice day/evening" and walk to the next door and repeat until you have enough customers to earn what you need every month. When you do this, there will be people sitting at home watching TV and not building their custy base. You however, can't be stopped and your custy base will grow. There are 2 different types of people in this game, those who feel scared to knock doors so don't knock, and those who feel scared to knock doors, but do it anyway.What type are you?Hope that helps.
